RN PlainText 0.9 is out ✨ Even faster rendering, even better compatibility, and the big one: a drop-in replacement for RN <Text>. Want to try it in your app? Just change one import and feel the perf difference!

react-native-bottom-tabs just works on the iPhone Duo  just a few small fixes needed, coming up on the next release

When I use @TesterArmy to test all edge cases in my app

Imagine having OTA for a native code 🤩

Announcing react-native-arrangement-view 0.1.0 ✨ Easily adapt your React Native app to foldables, arrange views between screens, and fetch hinge state Not prod ready yet, first on iPhone Duo , Android coming next release 🔜 Contributions welcome!

We're adding an AI Usage Policy to the React Navigation repo. AI helps us move fast, but we believe humans should still have understanding of systems they are working on. It also must not replace human interaction. Open Source is about collaboration. Let's keep it that way. github.com/react-navigation/…

e2e + jev from @typesafeai ⚡ I'm building an open-source framework for running e2e tests with agents. supports web, mobile (and more!) available soon: tester.army/e2e

🔍 Fałszywe strony internetowe tworzone przez cyberprzestępców często do złudzenia przypominają witryny banków i innych zaufanych instytucji. W ramach naszej serii prezentujemy kolejne przykłady fałszywych domen wykorzystywanych w atakach wymierzonych w klientów bankowości elektronicznej. Za pośrednictwem niebezpiecznych stron cyberprzestępcy mogą próbować przejąć poświadczenia logowania, co może prowadzić do utraty pieniędzy. ⚠️ Nie dajcie się zwieść podobieństwu fałszywej strony do oryginalnej witryny. Zanim wprowadzicie jakiekolwiek dane, dokładnie sprawdźcie adres strony. Kilka sekund poświęconych na weryfikację może uchronić Was przed oszustwem.

Jev playing Flappy Bird like it’s nothing

jevil is in the details 😈 built a quick POC running agent-device with jev and learned a ton. check the source code or read a short blog post ⬇️

It doesn’t matter how good an AI model is if it can’t test its work quickly and reliably. That’s especially hard on mobile. Traditional approaches rely on screenshots or the accessibility tree, making feedback slow and brittle. Agents can change code in seconds, then spend minutes trying to test it. In our new mobile apps, business logic runs headlessly. Agents can inspect state, navigate, and act through a CLI in milliseconds, without a simulator. When they need to test the app, the same CLI drives the simulator directly. The video is real time.

Cool history, but it's a false dichotomy and a bit of motivated reasoning. Moving everything onto a single thread makes interruptibility easy, but it isn't a scalable approach. It mostly works for a phone screen, and it breaks down once you try to extend it to bigger UI surfaces like desktop, or to more complicated interactions. At React Native we ran into exactly the same question and rejected both paths. That's why we built a concurrent renderer and concurrent layout: product logic, animation logic, interaction logic, and all the background work are separated and run on their own schedules. The idea is that product logic and UI rendering run independently, but when an interaction lands on the main thread, the engine can deliver and process the event synchronously, all the way through platform native code, React, layout, and drawing, on a single sync path, without waiting on anything else in flight or blocking it. Yes, JavaScript is still single-threaded, but React Fiber effectively makes it interruptible. The other half of the story is that we never finished it. I can be wrong, but as far as I know, sync events still aren't a thing in React Native.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions AFAICT the shortest path to AI-based economic revolution

i trained a fly to rewrite Shop back to React Native and make it faster than native

This webpage is served from a Raspberry Pi 4B at home, with 1 GB of RAM. How many concurrent visitors before it crashes? 🎉 pi.deepakness.com/ The page just shows information about the Pi itself. And it's on my home WiFi, behind a Cloudflare Tunnel.

If you're a React Native dev that works at Shopify, send me a DM. A lot of cool things to build here at @Replit for mobile.

Looks familiar. Runs native. Built with 9.1 + latest @octanejs. How to get a realtime visual feedback loop with any framework. 📓👇 The ChatGPT mobile experience.

the cat is out of the bag: we have rebuilt from the ground up @shop in SwiftUI and Jetpack Compose. it still feels weird to think that it actually worked out lol. needless to say, it was a crazy few months. Can you believe it? full rewrite, and now it's already out in prod 🤯
